Study on quality improvement of old geomagnetic data

Study period:2008 - 2008
Research field (2): Solid earth planet physics ,  General applied physics
Research overview:
In order to promote effective use of the geomagnetic observation data, it is necessary to assure the quality of data over the long period. In the old geomagnetic observation data of Kakioka Magnetic Observatory, it is also expected that the accuracy of observation could be improved by inspection of the method of data processing. In this study reprocessing is carried out about the observation data from the 1920s to the 1940s when observation work was getting into stride.
